Fabrication of a nonenzymatic glucose sensor using Pd-nanoparticles decorated ionic liquid derived fibrillated mesoporous carbon
چکیده انگلیسی
A novel nonenzymatic sensor was developed for glucose detection by the use of ionic liquid derived fibrillated mesoporous carbon (IFMC) decorated with palladium nanoparticles (PdNPs). PdNPs were uniformly decorated on IFMC and then the prepared nano-hybrid material (Pd@IFMC) was drop cast on the surface of a glassy carbon electrode to fabricate a glucose sensor. The prepared Pd@IFMC showed excellent electrocatalytic activity towards glucose oxidation. An oxidation peak at about + 0.40 V vs. Ag|AgCl|KClsat was observed for glucose on the fabricated sensor in alkaline solution. The oxidation peak current intensity was linear towards glucose in the concentration range between 1 and 55 mM (R2 = 0.9958) with a detection limit of 0.2 mM. The relative standard deviation (RSD) for repetitive measurements (n = 6) of 5 mM of glucose was of 5.3%. The fabricated sensor showed a number of great features such as ease of fabrication, wide linear range, excellent reproducibility, satisfactory operational stability and outstanding resistance towards interfering species such as ascorbic acid, uric acid, dopamine, fructose and chloride.
